Embodiment
See also shown in Figure 5ly, be the exploded perspective view of the utility model one specific embodiment, its camera lens module 2 comprises: a lens unit 21, a pedestal 22, an image sensor 231 and a gelatinous layer 24.The running of its processing procedure is that (Surface MountingTechnology SMT) does electrically connect with a circuit board (for example being soft printed circuit board 23) with surface mount technology with image sensor 231.Gelatinous layer 24 has the pass 241 that cooperates these image sensor 231 profiles, and the periphery that is placed on image sensor 231 in the time of is then fixed.The surface of gelatinous layer 24 has adhesion, the position that gelatinous layer 24 is set is able to firmly, the gelatinous layer 24 that uses in the present embodiment, can be the double faced adhesive tape that the two sides has stickiness, image sensor 231 and soft printed circuit board are 23 like this, the gap A that leaves over after the electrically connect operation has an opportunity to retain or conceal dust or scruff, can utilize the setting of gelatinous layer 24, it is enclosed in the A of this gap (as shown in Figure 6), prevents that these dust dirts from deviating from the A of gap and have influence on the quality of taking pictures of image sensor 231.Just in case imperceptible dirt is arranged overflows from the A of gap, absorption stickiness that also can mat gelatinous layer 24, catch pollutant and make it to rest on gelatinous layer 24 places, and can not drop to the sensitive surface of image sensor 231, can guarantee the good using character of image sensor 231, be to be a low cost, dustproof setting effectively easily.
In addition, in the lens unit 21 of camera lens module 2 and the connecting structure of its pedestal 22, the thread 221 that pedestal 22 medial margins have, the place also is that concealing of dust dirt arranged easily at the dead angle, so when both 21, after 22 windings, be set on the fixed base plate 25 of this soft printed circuit board 23, the dust dirt that conceal at this place, dead angle, after the vibrations through using or rocking, may drop from the place, dead angle, at this moment be positioned at its below (as shown in Figure 6), at the gelatinous layer 24 of image sensor 231 peripheries, but its absorption stickiness of same mat allows the dust dirt that drops rest on gelatinous layer 24 places, polluted with the induction receiving plane of avoiding this image sensor 231, had the good function of safeguarding the quality of taking pictures.
The then setting of gelatinous layer 24 image sensor 231 peripheries in camera lens module 2 of mat tool absorption stickiness, really can be convenient easily again effectively, solve this camera lens module 2 in processing procedure, the contamination by dust problem that exists, improve these products the instability quality phenomenon is arranged after output, reaching increases the stability that camera lens module 2 products produce, and has practical value.
In addition,, can establish reference column 222 under the pedestal 22, insert for reference column 222 and establish pilot hole 232 at the relative position of circuit board 23 for assembling easy location.When finished above-mentioned location, the pass 241 of gelatinous layer 24 was promptly aimed at image sensor 231, but just big envelope is used the effect that produces blocks dust around image sensor 231.
The above person of thought, only be of the present utility model one preferable feasible embodiment, non-so promptly limit to interest field of the present utility model, allly know well skill personage of the present utility model, the change or the modification of the equivalence of doing according to the utility model, must belong to patent right scope of the present utility model in fact, close and give Chen Ming.
